74F540 Datasheet | Fairchild Semiconductor

Description The 74F540 and 74F541 are similar in function to the 74F240 and 74F244 respectively, except that the inputs and outputs are on opposite sides of the package (see Connection Diagrams). This pinout arrangement makes these devices especially useful as output ports for microprocessors, allowing ease of layout and greater PC board density. Features s 3-STATE outputs drive bus lines s Inputs and outputs opposite side of package, allowing easier interface to microprocessors Ordering Code: Order Number Package Number Package Description 74F540SC M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 74F540SJ M20D 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74F540PC N20A 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide 74F541SC M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 74F541SJ M20D 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74F541PC N20A 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
